+## Bad update may leave device without WebView2 runtime installed
+
+Sometimes, a bad update may leave a user's device without the WebView2 runtime installed. The result is that the user is not able to use any WebView2 apps. Note that users may still use Edge.
+
+As a workaround, the user can install the runtime through Device Portal from this [direct link to download the WebView2 Runtime's MSIX](https://go.microsoft.com/fwlink/?linkid=2270343).

 ## Users may be unable to cleanup temporary files completely
